export default function App() { const [count, setCount] = useState(0); function set() { setCount(count + 1); } function undo() { setCount(count === 0 ? 0 : count - 1); } function resetToZero() { setCount(0); } function handleChange(event) { setCount(event.target.value); } return ( <div className="App"> <div className="Add"> <input id="count" value={count} onChange={handleChange}></input> <button onClick={set}> Add To Cart </button> <button onClick={undo}>Remove</button> <button onClick={resetToZero}>Remove All</button> </div> </div> ); }
